AMD Socket AM5 motherboards are set to arrive in Q2-2022, according to PJ, the editor of Uniko's Hardware. This would mean that the Zen 3 + 3D Vertical Cache chiplet AMD CEO Dr Lisa Su showed off in her Computex keynote, could very well be built in the Socket AM4 package, compatible with existing motherboards. The prototype Dr Su showed off appeared Socket AM4, too. AMD claims that the 3D Vertical Cache feature, when paired with a "Zen 3" chiplet, improves gaming performance by a significant 15 percent. Elsewhere across the landscape, PJ predicts that the Z690 chipset, which goes with "Alder Lake-S" processors in the LGA1700 package, will arrive by Q4 2021, with cost-effective chipsets such as the B660 and H610 in Q1-2022.
